Description

Technical Field

[0001] This utility model relates to cutting and blanking, specifically to a cutting and blanking rack. Background Technology

[0002] Traditional cutting and unloading racks cannot adjust their feeding mechanism vertically to accommodate profiles of different sizes and specifications. Utility Model Content

[0003] In view of the above problems, this utility model proposes a cutting and unloading rack.

[0004] The technical solution of this utility model:

[0005] A cutting and unloading rack includes a front unloading rack and a rear unloading rack. The front unloading rack is installed in front of the cutting machine tool, and the rear unloading rack is installed behind the cutting machine tool. A feeding mechanism is installed on the front unloading rack, and a receiving mechanism is installed on the rear unloading rack. The feeding mechanism and the receiving mechanism are opposite to each other. The feeding mechanism consists of several feeding rollers arranged side by side. All feeding rollers share a feeding roller seat. A lifting mechanism is installed on the front unloading rack. The lifting mechanism is connected to the feeding roller seat and drives the feeding roller seat to move up and down. Each feeding roller moves up and down with the roller seat. The lifting mechanism consists of several adjustable turntable structures. The adjustable turntable structure is a cam structure, which consists of an adjustable turntable, a follower, and a lifting bracket. The outer periphery of the adjustable turntable is a cam path.

[0006] Further refining the above technical solution, the adjustable turntables of each adjustable turntable structure are coaxial, and the shaft is a drive shaft with a power source installed at one end; the power source is a handwheel or an electric structure.

[0007] To further refine the above technical solution, a raw material placement area is provided on the front unloading frame, which is located on the side of each feeding roller; several guardrails are installed on the front unloading frame, with each guardrail arranged side by side between the raw material placement area and each feeding roller; the guardrails are liftable guardrails.

[0008] Further refining the above technical solution, the bottom of the front unloading rack is raised to form a secondary tail material placement area.

[0009] To further refine the above technical solution, the adjustable turntable has a mounting bracket with a guide notch to guide the lifting bracket's up-and-down movement; the lifting bracket supports and connects to the roller seat, and its up-and-down movement drives the roller seat to move up and down.

[0010] To further refine the above technical solution, each feeding roller is equipped with a shield on both sides. The shield on the side closer to the raw material placement area is the inner shield, and the shield on the side farther from the raw material placement area is the outer shield. The height of the outer shield is the same as the height of the inner shield. This ensures that the material will not roll onto the ground without affecting the feeding process.

[0011] Further refining the above technical solution, the receiving mechanism consists of several receiving rollers; a positioning stop is installed on the rear unloading frame, the positioning stop being suspended above each receiving roller; a trapezoidal shim is installed on the rear unloading frame, the trapezoidal shim being located in front of each receiving roller; a receiving platform is installed on the rear unloading frame, the receiving platform being located on the side of each receiving roller; the trapezoidal shim design effectively prevents small-diameter circular pipes from getting stuck in the shim gaps during unloading.

[0012] Further refining the above technical solution, the positioning stop is a swing rod; a guide block is installed on the rear unloading rack, the guide block is located below the swing rod and above each receiving roller, and its front end is an inclined surface; after cutting, the swing rod is first lifted, and then the profile is moved backward to push the cut profile segment backward. When the cut profile segment touches the guide block, it moves along the inclined surface, deviates from each receiving roller, and slides onto the receiving platform.

[0013] To further refine the above technical solution, a pulley assembly is installed on the rear unloading rack. A traction rope passes around the pulley of the pulley assembly, with one end connected to a swing arm and the other end fixed to the cutting machine tool. By pulling the traction rope, the swing arm swings up and down.

[0014] To further refine the above technical solution, the receiving platform is an angle-adjustable receiving platform with a flip-up short material guide platform installed at its front end. When cutting small parts, it is opened, and the cut small parts can slide directly into the wooden box through the unfolded short material guide platform, saving picking and placing time. When cutting long materials, it is retracted to avoid affecting the downward trajectory of the long materials.

[0015] The advantages of this utility model are that it has a reasonable design, simple structure, and an added lifting mechanism. The lifting mechanism is used to move each feeding roller up and down to adjust the height, which can adapt to profiles of different sizes. The lifting mechanism is cleverly composed of several cam structures. Attached Figure Description
